Server-grade ECC RDIMM

This 16GB OWC module is DDR4-2400 ECC registered memory built for servers, workstations and NAS systems. It runs at 1.2V with CL17 latency and a 2Rx8 organisation. The 288-pin RDIMM will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs.

Fits registered DDR4 slots

The stick plugs into a 288-pin DDR4 RDIMM slot on a server or workstation motherboard that supports registered ECC memory. It requires a platform that accepts registered modules and will not function in consumer boards that only take unbuffered RAM. No heat spreader is fitted, so airflow in the chassis handles cooling.

16GB capacity at DDR4-2400

A single module adds 16GB of error-correcting registered memory at 2400MT/s, suited to virtualisation, database or file-serving workloads that benefit from ECC protection. Capacity scales by populating additional compatible RDIMM slots. Systems limited to lower memory speeds or unbuffered DIMMs cannot use this module.

Questions about this item

What is the maximum speed this DDR4 2400 ECC RDIMM can sustain during continuous server workloads?

The module runs at 2400 MHz with CL17 latency and 1.2 V, matching the JEDEC PC4-19200 standard for sustained operation.

How much heat and power does this 16 GB registered DIMM produce when the server runs all day?

Operating at 1.2 V without a heat spreader, it draws minimal power and relies on chassis airflow for cooling during extended use.

Which server or workstation platforms already support this 288-pin 2Rx8 registered module?

It is a direct replacement for Dell part numbers A8711887, A8797578 and SNPHNDJ7C/16G in compatible servers, workstations and NAS systems.
